EncrypTight Overview

multiple Policy Enforcement Points (PEPs) can use common keys, while a centralized platform assumes the function of renewing keys at pre-determined intervals.

In this system, you use ETEMS to configure the PEPs, Policy Manager (ETPM) to create and manage policies, and Key Management System (ETKMS) to generate keys and distribute keys and policies to the appropriate PEPs. The PEPs encrypt traffic according to the policies and keys that they receive.

Using EncrypTight, you can create distributed key policies for the network topologies shown in Table 1.

Table 1 Network topologies

Topology	Description
Layer 3 IP topologies
Hub and Spoke	In a hub and spoke network, a hub network communicates with the
	spoke networks and the spoke networks communicate only with the
	hub network.
Multicast	In multicast transmission, one or more networks send unidirectional
	streams to a multicast network address. The multicast routers detect
	the multicast transmission, determine which nodes have joined the
	multicast network as destination networks, and duplicate the packet as
	needed to reach all multicast destination networks.
Point-to-point	In a point-to-point network, one network sends and receives data to
	and from one other network.
Mesh	In a mesh network, any network can send or receive data from any
	other network.
Layer 2 Ethernet topologies

Mesh

For Ethernet, you can create policies for mesh networks. Note that if the network uses VLAN ID tags, you can also create policies for virtual point-to-point connections.
